Oct 16 (Reuters) - The ‌US CDC on ​Friday ​reported 4,410 measles cases nationwide as of October 15, an increase of 330 from ‌its last update a week ago, as an ⁠outbreak of the highly contagious disease continues.

Here are key details:

• Measles-related ‌hospitalizations this year stand ‌at 451, the Centers for Disease Control and Prevention said

• The state of Pennsylvania has reported five measles-related ​deaths

• The CDC has confirmed two measles-associated deaths in 2026, though it has not identified the ⁠states involved

• Pennsylvania has reported 1,260 measles cases this year as of October ​16, with 238 disease-related hospitalizations, according to state health department data

• Last month, the CDC ​shifted to using mortality data ‌from the National Center for Health Statistics for measles-related deaths, rather than relying on ⁠state health departments, a change that has drawn scrutiny

• The CDC said on Tuesday it would deploy more support to ⁠Pennsylvania to help investigate the outbreak

• Children and teenagers aged ​5 to 19 were the largest group affected by the disease at 1,856, or 42% of cases, followed by adults aged ‌20 and older at 1,787 cases, or 41%, CDC data showed

• Earlier this month, ‌the state of New York declared a disaster emergency ⁠for the measles outbreak, ‌the first such declaration ​by a US state
